In addition, the following skins were released to the game files along with this patch, but were imposed special requirements to obtain them.

Unchained Alistar - (Released for free on September 23rd as a gift/promotion to players that linked their YouTube and League of Legends accounts and suscribed to Riot Games channel. Still available by this mean.)

Artic Warfare Caitlyn - (Currently, only available by reedeming a code obtainable from the PC Gamer-November Issue, released on September 13th, 2011)

Crystal SlashCrystal Slash: Skarner lashes out with his claws, dealing physical damage to all nearby enemies and charging himself with Crystal Energy for several seconds if a unit is struck. If he casts Crystal Slash again while empowered by Crystal Energy, he deals bonus Magic Damage and slows all targets hit.

Fracture: Skarner summons a blast of crystalline energy which deals damage to enemies struck and marks them. Any further damage dealt to marked targets by Skarner will allow him to consume the mark to heal himself.

Impale (Ultimate): Skarner suppresses an enemy champion and deals magic damage to it. During this time, Skarner can move freely and will drag his helpless victim around with him. When the effect ends, Skarner's target will be dealt additional damage.

Energize (Innate): Basic attacks lower the cooldowns of Skarner's abilities by 1 second against champions and 0.5 seconds against non-champions.

Dying to non-champions no longer resets kill streaks or increases death streaks.

Assists now reduce (not reset) death streaks.

Using Summoner Teleport on a ward will no longer reveal the ward through fog of war to enemies. Instead, it will destealth the ward to be seen if an enemy is near and reveal the teleport particle through fog of war to enemies.

Allied champions can no longer block targeting of an enemy champion if they are standing on top of one another.

Added a new in-game option for "Borderless Window Mode" that allows people to alt-tab more efficiently.

Attack-move improvements:

Attack-move targeting is now more predictable (now targets closest enemy).

Attack-move will now target visible wards.

Changed attack-move cursor color to red from green.

Added new keybindings for "Self+Smart Cast" for abilities and Summoner spells. Casting with these binds will first try to Smart-Cast the ability; if there is no target or an invalid target under the cursor, it will attempt to Self-Cast the ability.

Fixed a bug where clones did not show items in their inventories.

Fixed a bug where certain particle effects would not show up if using the minimap for targeting.
